Title: Linear hydraulic motor
IPC: F03C1/00
Filed: 1969-09-15
Abstract: 1284554 Bearings; pistons PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 15 Sept 1969 [18 Sept 1968] 45404/69 Headings F2A and F2T [Also in Division F1] In an hydraulic motor comprising a cylinder 32, 33 in which slides a piston 31 having a rod 38 and at least three hydrostatic bearing recesses 41 spaced around the periphery of the piston, the recesses are fed with oil through throttled passages 42 in permanent communication with the continuously pressurized cylinder space 40. The areas of the piston end faces 36, 37 are in a 2 : 1 ratio, whereby under static conditions the pressure in the cylinder space 40 is twice that in the cylinder space 62. To inhibit the escape of oil from the space 62, the pressure in the recesses 41 is arranged to be equal to that in the space 62. This is achieved by arranging for the resistance to flow of oil from the space 40 to the recesses 41 and from the recesses 41 to a groove 43 connected to atmosphere, to be substantially equal. Alternatively, the resistance to flow from the recesses 41 to the groove 43 may be reduced and the groove 43 connected to atmosphere through a variable throttle valve 50. The valve 50 comprises a piston controlling a throttle opening and being subjected, at one end, to the pressure in the space 40 and, at the other end, to the average pressure in the recesses 41, which pressure exists in a groove 63 adjacent to the recesses. The piston-rod 38 passes out of the cylinder through a sleeve 70 having circumferential grooves in its inner and outer surfaces. The outer groove 80 is permanently at supply pressure while the inner grooves 75, 76 are in communication with a passage 78 having a valve 79. When the valve 79 is closed the pressure in the inner and outer grooves is the same and the rod 38 is able to move. Opening of the valve 79 allows a flexible part 77 of the sleeve 70 to contract and lock the piston-rod.

An information transfer system e. g. for a chromatographic apparatus in which information is fed to a responsive means 2, to provide an electrical analogue signal fed to a store 3 is provided with a switching circuit which, on attainment of a maximum value of the received information, holds the maximum value of the analogue signal in the store, and then transfers it to a receiving circuit 9. In a first embodiment, Fig. 1 relay C is normally energized, and upon closure of switch 11 motor 2 rotates in accordance with the received information to store an electrical analogue signal in the potentiometer 3. An arm 4a, driven from the motor via a friction clutch, closes switch 8 to actuate relay A which in turn energizes relay B. After the attainment of a maximum of the received information, motor 2 reverses and arm 4a releases switch 8. Relay A is thus released and its contact a2 open to stop motor 2, with the maximum valve of the analogue signal stored in potentiometer 3. After a delay, due to capacitor K2, relay C releases, and its contact c2 connects the output of potentiometer 3 to receiver 9. After a further delay, due to capacitor K1 relay B releases re-energizing relay C and motor 2, i.e. the circuit reverts to its initial state. In a second embodiment, Fig. 2 (not shown) the sense of rotation of motor 2 is detected by a phase sensitive detector, valve 13, controlling two transistor switches A1, B Reversal of the motor 2 switches A1 off and Bl on and the analogue voltage attained is connected to the receiver 9, via contacts c2 as before.

Abstract: 1415250 Digital to AC pulse duration conversion PHYSICS INTERNATIONAL CO 17 Oct 1973 [30 Oct 1972] 48434/73 Heading H3H An information signal having a particular time duration is converted to an AC pulse of duration corresponding to the information and less than the particular time duration. The information signal is normally serial digital and the resulting signals from several channels may be transmitted by time division multiplex, lone (frequency) multiplex or a mixture of both. As described a four-bit serial binary input signal (A) having a duration from T(0) to T(1) is converted by digital to analogue converter 10 to an analogue voltage B which is applied to one input of comparator 12. At time T(2), the start of the transmission time slot, a pulse is supplied from pulse generator 15 to integrator 14, which produces a ramp voltage, gate 16 is opened supplying AC from oscillator 17 to amplifier 23 and reference A.C. from clock oscillator 22 is also supplied to the amplifier. When the ramp voltage (E) equals the analogue voltage (B), gate 16 is closed and gate 21 closes at the end of the time slot T(3). The resulting transmission is on A.C. pulse (H) of duration proportional to the digital input and a clock A.C. signal (J) of duration equal to that of the time slot. The signal may be transmitted down telephone line 26. At the receiver; the data signal and clock transmissions are separated by filters 32, 33 respectively. The signal is amplified (36) and dipped (38) and ringing, introduced by the telephone lines is removed by a circuit which detects when the amplitude of a cycle is more than 67% less than that of the previous cycle. The signal is rectified (30) and the reresulting duration significant pulse is shaped by a circuit responding to the 10% of max. intensity thresholds (46). The pulse is integrated at (49) and the resulting analogue voltage (U) is passed to analogue to digital converter (50). This converter (Fig. 22) comprises a sequential scanner 126 which generates the binary values from 0 to 15, generates the analogue voltage proportional to each value from resistors R100- R103, and summing circuit 129 and compares it with the analogue value (U) at 130. When the error signal is less than a predetermined value, the scanning cycle is stopped and the serial digital value is read out.
